High performance clock generators

Maxim Integrated Products introduces the MAX9450/MAX9451/MAX9452 series of high-performance clock generators available with three types of outputs: LVPECL (MAX9450), LVDS (MAX9451), and HSTL (MAX9452). By integrating the VCXO, PLL, buffer, and clock source, the MAX945x clock generators save cost and space over a discrete solution. The MAX945x devices also have redundant inputs, perfect for applications that require holdover if an input fails.

The MAX945x series accepts inputs from 8kHz to 500MHz, and drives outputs up to 160MHz. The devices also feature clock output jitter less than 0.8PSrms in a 12kHz to 20MHz band. These low-jitter, high-performance clock generators ensure reliability in the system and jitter performance, making them ideal for SONET and SDH data-communications systems and base-station applications, says Arrow Electronics .

The MAX945x devices are guaranteed for operation over the -40OC to +85OC temperature range, operate from a 2.4V to 3.6V supply, and are available in 32-pin TQFP packages with exposed paddles.
